The given equation is
Step 1: Multiply both sides by (x-4).
Step 2: Multiply both sides by 7.
Step 3: Using distributive property.
Step 4: Isolate all terms on one side.
Step 5: Find factors by splitting the middle term.
Step 6: Using zero product property, we get
It means student solved the equation correctly.
Therefore, the correct option is A.
Born: 7.45 pounds
gains: 6.4 oz a week
time: 1.5 months
6.4 + 6.4 + 6.4 + 6.4 + 6.4 + 6.4 = 38. 4 oz
38.4 oz = 2.4 punds
7.45 + 2.4 = 9.85
